Roof Repair Chicago IL | Call C & A Roofing

Roof decking rot in Chicago is typically caused by persistent moisture from ice dams, clogged gutters, or minor leaks that go unnoticed. Our process starts with a thorough inspection to locate all compromised wood. We then carefully remove the damaged sections and replace them with new, treated plywood or OSB, ensuring a solid base before reinstalling underlayment and shingles. Proper ventilation is also key to preventing future rot, which we always address.

Seeing some granule loss is normal as asphalt shingles age, especially after severe weather. However, excessive loss, bare spots on shingles, or granules accumulating in gutters can signal that your roof's protective layer is wearing thin. In Chicago's climate, this can lead to accelerated UV damage and reduced waterproofing. We recommend a professional evaluation to assess the remaining lifespan and discuss whether repair or replacement is the most cost-effective solution for your home.

We recommend a professional roof inspection at least once a year, ideally in the late spring or early fall. The extreme seasonal shifts in Chicago—from heavy snow and ice to summer storms—can cause wear that isn't always visible from the ground. An annual check allows us to catch minor issues like cracked flashing, loose shingles, or early signs of granule loss before they lead to major leaks or structural damage like decking rot.
